GAS-REGULATOR FOR WELSBACH BURNERS.

SPECIFICATION forming part of Letters Patent No. 578,212, dated March 2,1897.

Application filed June 9, 1896. Serial No. 594,819. (No model.)

T0 or whont it may concern.-

Be it known that I, OREN R. CLINE, of El Dorado, in the county of Butlerand State of Kansas, have invented a new and useful Improvement inGas-Regulators for VVelsbach Burners, of which the following is aspecification.

My invention is in the nature of an improved automatic regulating devicefor Welsbach and other burners of this class mixing air and gas or usingan incandescent mantle; audits object is to render the gas-pressure souniform that its variations shall not in juriously affect the fragilemantle, but will insure a uniform and brilliant light.

It consists in the peculiar construction of an automaticregulating-valve in combination with the burner-tube and theencompassing air-chamber, as will be hereinafter fully described.

Figure 1 is an enlarged side elevation of the regulating-valve. Fig. 2is a vertical section of the same shown applied to the tubular stem of aWVelsbach burner, which latter is shown in dotted lines; and Figs. 3 and4 are sectional Views of modifications. I

In the drawings, a represents the screwnipple, and a the upwardextension of the tubular stem of a WVelsbach burner. The nipple a is tobe screwed upon the gaspipe, and the stem at has openings a in its sidethat receive air from a surrounding air-chamher 5 b. The lowerportion 1) of this airchamber has a sliding draft-regulator 19 withholes 5 registering with or capable of being turned partly or whollyaway from corresponding holes in the part b, so as to regulate thequantity of air to be admitted through holes a to the interior of thetube a. This is the ordinary construct-ion of the air-supply of aVVelsbach burner.

Between the abutting ends of the nipple a and tubular stem a isordinarily placed a perforated disk, known as the gas-check. This isentirely replaced by my invention, which consists of a flanged cup 0 0,having a central tube 0 opening through itand its bottom flange caughtand held between the abutting ends of the nipple a and tube a. lVithinthe annular chamber of the cap 0 is placed a liquid seal of mercurym, inwhich is inverted another cup 01 cl, whose walls d dip into the mercuryand centrally to which cup (I d is adjustably attacheda screw-threadedstem 6 of a valve 6, this valve being below the cup 0 and its stemextending up through the central tube 0 In the top 01 of the invertedcup are several small holes d through which the gas escapes into thetube a to become mixed with the air therein.

The normal position of valve e is down and open, and the gas passes uparound its stem 6 through the central tube a and passing through thesmall holes at in the inverted cup mingles with the air in theburner-tube to produce the perfect combustion and intense heat requiredby the Welsbach burner.

If the gas-pressure in the pipes be increased, the inverted cup d d islifted slightly in the mercury seal, and the valve 6 rising cuts off acorresponding proportion of the flow,while if the gas-pressure in thepipes be diminished the cup d d drops down and opens Valve 6 wider, thusincreasing the [low and keeping a constant relation between pressure andflow, increasing thelatter as the former diminishes, and vice versa, soas to make a uniform dew livery and proper admixture of gas with air atthe burner. In this way if a portion of the lights of a burner be turnedon or off this effects no change in the feed of gas to this burner, andthus preserves always a proper action and uniform light.

As a modification of my invention I may use the burner-tube to form theouter wall of the mercury-cup, as shown in Figs. 3 and 4:.

I am aware that it is not broadly new to incorporate in a burner-tube amercury seal with an inverted cup and valve having a rising-and-fallingmotion, in which case the working power is the difference between theinitial gas-pressure below the valve and the gas-pressure above it,which difierence is so slight as to give little or no effectiveness. Inmy invention the working power is the entire or initial pressure of thegas on the one hand, working against the atmospheric pressure only, byreason of the fact that air is freely admitted into the burner above thevalve from the encompassing air-chamber of the VVelsbach bu rner, whichgives a very efficient action.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a burner mixing air and gas, the combination with the burner-tubeand its surrounding air-chamber, with regulating airinlets; of aregulating-valve placed in the burner between the initial gas-pressureand the air-chamber, said valve consisting of an annular liquid-sealchamber with a central opening, an inverted cup with perforated top, theperforations of which lead into the mixing-chamber above, and a valveand valvestem, the latter attached to the inverted cup and descendingthrough the annular seal and attached at its lower end to the valvesubstantially as and for the purpose described.

2. In a burner mixing air and gas, the com bination with the burner-tubemade in upper and lower sections a and a with openings a in the uppersection, and an air-chamber with regulating-inlets surrounding the same,an annular liquid-seal chamber having a marginal flange at its loweredge retained between the abutting ends of the two burnertube sectionsand separating the initial gaspressure from the air-pressure, aninverted cup with perforated top, the perforations of which lead intothe mixing-chamber above, and a valve and valve-stem the latterconneeted to the inverted cup and extending through the liquid-sealchamber and connected to the valve below the same substantially as andfor the purpose described.
